SUPPLEMENT FEATURE MACHINE VISION SYSTEMS Barcode and data matrix code detection B
alluff’s product line of proven BVS vision sensors includes the BVS-E
Identification designed for fast and simple detection of barcodes, data matrix and QR codes. The user can even read multiple codes within one inspection eliminating the need for several sensors. The BVS-E Identification is just as simple and fast to use as a normal photoelectric sensor, and easy to integrate into an application thanks to its compact dimensions. Tedious training or learning of a special programming language as with smart cameras are a thing of the past. A PLC can be used to easily switch between
different inspections, and function modules for various controllers are available from Balluff. The image sensor reads all common barcodes as well as data matrix, standard and mini QR codes regardless of orientation. In addition, printed character and number sequences such as batch numbers or expiry dates can be verified using optical character verification (OCV). The result of the inspection is indicated on the output as an ‘OK’ or ‘NOK’ signal. The code data can also be output via RS232 or Ethernet, such as when verification is required as to which parts have been processed. The BVS-E Identification vision sensor
is available in Visible Red Light or Infrared versions, and with four different lenses 6, 8,12 or 16mm. The BVS-E has two programmable PNP or NPN outputs for transmitting Inspection results and Trigger Input/output for sensor control and lighting synchronization. The built- in high-output Visible Red or Infrared LED lighting ensures optimal illumination of the inspection area. The power supply and peripherals are connected using two industry-proven M12 ports.
To set parameters, the user connects the sensor to a PC and starts it up using the free BVS ConVis configuration software or by a teach button mounted on the sensor. Balluff also offers a variety of high-
power, industrial rated light sources for all BVS versions. The user can choose from among background, spot, ring and dark field lights. And to ensure quick installation of the sensor on the machine Balluff has the ideal solution: custom- designed optional mounting brackets and the Balluff Mounting System eliminate costly and time-consuming homemade fastening methods.

family of vision sensors from Banner Engineering are a perfect example of this. iVu Plus Gen2 is a new
generation of vision and barcode sensors offering multiple tools and resolution options in each unit. The iVu Plus Gen2 line includes integral and remote screen models for use in a wide range of inspection, machine vision and quality control applications.
The vision sensors are designed
to solve applications that would traditionally require multiple photoelectric or proximity
M
achine vision has come a long way in the past decade or so. The days when a degree
was needed to programme a vision system are long gone as feature laden systems with true user friendly controls emerged. Vision sensors occupy the space between
simple photoelectric sensors and a full vision system and have matured a great deal since they were first introduced. The software is more intuitive and where once they were only suitable for a very limited number of applications, they can now be used reliably in many of the applications previously reserved for high-end vision systems.
sensors. They now include a full resolution option to detect small features, and the capability to use multiple sensor tools in the same inspection. Bar code readers validate 12 1D and 2D barcode formats to support advanced traceability in all industries. They offer a coarse mode resolution setting that can provide significantly faster read rates, especially for 2D barcodes. The sensors can store and control up to 30
inspections for fast product changeover. Rugged IP67 rated housing allows use in hostile environments. Remote displays are available in both machine-mountable and hand-held
